devices andl has reference more particularly to devices forcleaning, .cooling and drying grains by air blasts.- f

The object of my invention is to lproduce a device by which, various 'grains'may' be cleaned, cooled,',dried andY otherwise im-V proved,1which is simple in construction, easy to makeand carries'no mechanical parts to get out of order orrequirelubrication. y

With .this and other yobjects in view my invention consists in certain novelfeatures of construction, arrangement and combination ofl parts as will be hereinafter set forth and pointedout in the claims, reference vbeing had'to the drawing in which:

Y VFigure l is a perspective view showing the cleaner Vas installed. v

fFig.: 2 is a vertical longitudinal section enlarged., A Y j l f 'Fig 3 is a horizontal longitudinal section taken on line 3--3 of Fig.' 2;

As a practical embodimentof my invention I utilize a casing which is abox-like structure introducedV between supply and storage elements, and may be of any suitable material.. y

The casingvincludes a top and bottom, front land rear wallsand vend walls, the casing being of considerably greater extent from end to end than from front to rear.

rIhe top includes two sections 6 and 7 which extend from the upper corners of the ends a short distance horizontally and then obliquely converging meeting in an angle 8; it will thus be seen that top wall projects downwardly into the casing.

The end walls are designated by 9 and 10 the wall 9 having openings 9a and 9b at its upper and lower ends respectively.

11 represent oppositely slanting partitions secured to the inner surface of end wall 9 and the same width as the casing thus filling the space between the front` and rear walls.

The upper partition 11 begins at the lower end of the opening 9a and extends into the casing approximately parallel with the sec linto thevcasing.` -f .Y The lower kend'of Vthe casingis partially' closedl by a bottom section Alei' which extends i about one half way across the lowerfend leavlng a space or opening l5 through which ythe 'cleaned grain falls into' a bin or other Isuitfvable receptacle or provision madevifor suchf/ The bottom of the casing is fitted in tion 6 ofthe top thus forming, a downwardlr inclined chute. The lower partition 11 begins a short distance above the opening 9b which is of somewhat less area than the opening9a, andextending upwardly withinthe casing at an angle meetsthe upper one'of thepartitions 1n a polntat approximately the vertical'center offthe'lcomplete device.

To the opening-9a is' 'applied'a tubing 12 kthrough 'which grain is delivered to the f cleaner,` and at thezbottom of the same side to the opening QP'isapplied the'ftubu'lar spout 13 through which y y Y an opening-16 in afloorfor platform 17.'

The end wall 10 bends inwardly Vand downwardly asv shown'in Fig. 2 presenting.'-

an inclined wall l0?l which acts to deiect the entering air blast,upwardly that it'may discharge throughthe .opening 10b in wall l0, and the discharge/spout or tube k18. f Y

Depending from the member is a baffle board 19which fills the space between Vfront vand rear vwalls and extendsv downwardly'to a point in substantially the horizontal `plane ofthe Vmeeting points -of partitions 11. This baiie it'will be .noted isv ain advance of the inclined entrance chute and "intervenes betweenthe same and the discharge outlet 10b.

The reference characters 20 round rods extending from front to rear blasts ofiair are fed 7 7V of the top indicate of the casing within the same and they are .disposed in a slanting series in a plane which is substantially a continuation of the lower wall or floor of the grain inlet chute; the distance between the respective rods of this series is such as to generally let the' Y grains pass freely yet close enough to offer some obstruction and cause the grains to be whirled or tumbled as they drop towardl the opening in the bottom.

In the front wall 21 of the casing is provided anv opening which is controlled by a pivoted door 22 which is held in its closed position by a keeper 23. This opening may be used to clean out the casing should strawv or refuse become caught or clogged in the inclined chute. c

At the lower endof the casing the lfront wall is also provided with a hand-hole 24 covered by a gate valve or cover pivotalgly secured to the front' wall; through this handhole the lower end of the casing canl be relieved should it becomeclogged. y

It is thought that the operation of the device will be obvious it being understood that grain Venters the casing at 9aand at the saine time and continuously a blast of air is de# livered into the casing and through the current of the' entering grain; thev entering Ygra-in is carried down the inclined chute by its weight. and force of gravity, andif any should enter with sufficient force to go across the casing it will strike the-baille 19 and fall toward the round rods 2O disposed in a slanting or oblique series. l

The grain being heavier than the ini- Vpurities withwhich it may be mixed such as smut, chaff, etc., through the opening '15 in bottom of casing after` having rbeen tumbled on rods 20 thereby loosening and `knocking off any ladhering foreign substances, and also cleaning to some extent.

The entering air blast coming in through tube or spout 13 blows'the light foreign substances over toward Vthe inclined wall'10a .which deflects the blast upwardly as indiing a discharge opening for the lcleaned rainY and a discharge outlet for air and impurities in the side opposite the entrance side, and disposed di-agonally opposite the air Vblast entrance, anda vertical deector plate disposed between theairmoutlet and region of air and grain intersection at approximately thevertical plane of the termi-V nal of the grate.

2, grain cleaner comprising a casing having top and bottom, front and rear, and end walls, the top ywall comprising a pair of sections converging downwardly forming an entrant angle, one side wall also having an entrant angle forming with the top section an inclined grain entrance chute, ythe said sidewall having below the entrant portion an air blast entrance, a series oit' transverse bars disposed in an inclined plane beyond the lower end'of the grain entrance chute, a baile plate depending from the top wall beyond the entrant angle and projecting towardssaid bars, the bottom ofthe casing provided with a'discharge aperture for the cleaned grain, the discharge side wall"v having its lower Vend inclinedinwardly'to said grain discharge aperture, the upper end of said wall provided with a discharge for mixed air and impurities;

3. In a device of the character.V and for` Ythe purposes specified, the combination with a casing having spaced apart front and rear walls, of a grain entrance and air blast inlet in one end wall, a downwardly inclined `chuteleading inwardly from the grainen-` trance, an inclined series of rounded transverse bars continuing beyond the lower end of said chute and atv approximately the saine inclination, a baHe plate depending vertically from the top of the casing between said transverse bars and a discharge aperture at the upper corner of the other' end wall of the casing and projecting toward said bars, the lower portion of said last named end wall inclined ,downwardlyV and inwardlyv to forma delecting surfacewhereby mixed air fand impurities arev ydiw rected upwardly to the discharge aperture, and means carried by front wall to permit cleaning both above and below series of transverse rods. 5
